So David and Abishai came to the people by night: and, behold, Saul lay
sleeping within the place of the wagons, with his spear stuck in the
ground at his head: and Abner and the people lay round about him.
Then said Abishai to David, "God hath delivered up thine enemy into
thine hand this day: now therefore let me smite him, I pray thee, with
the spear to the earth at one stroke, and I will not smite him the
second time."
And David said to Abishai, "Destroy him not: for who can put forth his
hand against the Lord's anointed, and be guiltless?" And David said, "As
the Lord liveth, either the Lord shall smite him; or his day shall come
to die; or he shall go down into battle, and perish. The Lord forbid
that I should put forth mine hand against the Lord's anointed: but now
take, I pray thee, the spear that is at his head, and the cruse of
water, and let us go."
So David took the spear and the cruse of water from Saul's head; and
they gat them away, and no man saw it, nor knew it, neither did any
awake: for they were all asleep; because a deep sleep from the Lord was
fallen upon them.
